Hello fellow Wikipedians,

I have just modified 4 external links on Isotopes of neptunium. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

• Added archive https://web.archive.org/web/20110519171204/http://ec.europa.eu/energy/nuclear/transport/doc/irsn_sect03_146.pdf to http://ec.europa.eu/energy/nuclear/transport/doc/irsn_sect03_146.pdf
• Corrected formatting/usage for http://www.sciencenews.org/view/generic/id/3246/title/Neptunium_Nukes%3F_Little-studied_metal_goes_critical

Neptunium 219

http://www.sciencedirect.com/science/article/pii/S0370269317309942 half-life of 0.15ms (= -0.07 +0.72) This needs adding to the table. — Preceding unsigned comment added by 92.11.246.147 (talk) 16:11, 23 December 2017 (UTC)

Will take a look (and has the gap from 220 to 224 inclusive been filled yet?). Double sharp (talk) 10:51, 12 February 2018 (UTC)

Well, now it has, save 221 only. :) Double sharp (talk) 09:09, 26 July 2024 (UTC)

²³⁴Np: Spin 0+?

That looks impossible as ²³⁴Np is an odd-odd nuclide. 129.104.241.214 (talk) 17:01, 6 March 2024 (UTC)

³⁴Cl also has 0+ spin. How is it impossible? Nucleus hydro elemon (talk) 15:34, 7 March 2024 (UTC)

Thanks for the reminder. I had always thought that the spin of an odd-odd nuclide can't be zero, as it is stated here: "If the numbers of protons and neutrons are both odd, the ground state nuclear spin is an integer larger than zero" ... 129.104.241.214 (talk) 03:43, 10 March 2024 (UTC)

Ah, I found that ⁵⁰Mn, ⁶⁰Mn, ⁵⁴Co, ⁷⁴Co, ⁶²Ga, ⁶⁴Ga, ⁶⁶Ga, ⁶⁴As, ⁶⁶As, ⁷⁰Br, ⁷⁴Rb, ⁷⁴Rb, ⁷⁸Y, ⁸²Nb, ⁸⁶Tc, ⁹⁰Rh, ⁹⁴Ag, ⁹⁸In, ... also have spin 0+. This includes N = Z nuclides for odd Z = 17 and 25 through 49 (except 29). 129.104.241.214 (talk) 03:55, 10 March 2024 (UTC)

Contradictions regarding Np-237

The section Isotopes_of_neptunium#Shortage_of_237Np_stockpiles implies Np-237 decay doesn't involve gamma ray emission, but the section Isotopes_of_neptunium#Neptunium-237 includes a decay scheme showing gamma emissions at 29 KeV and 86 KeV. 2603:8080:E500:161F:24AA:52BD:4E5C:B896 (talk) 18:59, 28 June 2024 (UTC)

The first link you mention is talking about Pu-238 decay, not Np-237 decay. Double sharp (talk) 07:27, 26 July 2024 (UTC)
